Hey RONC, I tested the FFTrc plugin on my system (Win10, Photoshop CC), and didn't encounter any problems. Did you have a chance to work on the inverse function yet?

Thanks for running a test. Perchance was it a dataset that got bad results from the normal fft rgb? I need to know whether there are any problems hiding in the rc version. I do have inverse running but my first go at my tests is delayed as I have health problems and can't do anything correctly so I am doing nothing per doctors. My mind is testing it but have limited computer use. Hopefully by week end I should be able to get going again.

> Perchance was it a dataset that got bad results from the normal fft rgb? I need to know whether there are any problems hiding in the rc version.

There are problems that exist in both.
I just made a test image that fails and give a blank red channel after transformation with both the new and the old plugin.

1. New document. 9000x6000 px. Just random numbers I came up with. Pattern fill and flatten. Transforms great!
2. New document. 8292x5364 px. Just random numbers I came up with. Pattern fill and flatten. Transforming it now gives a blank red channel with both plugins.

So certain dimensions produce this bug. I don't know what the pattern is, but the main clue is that **round numbers appear to work better.**

Another problem I found is that the plugin doesn't work in CC2018. I get "Could not complete the FFT RGBrc1 command because of a disk error" when I try to run it. Same for the old plugin. Not sure what has changed in CC2018.

Chain,
Thanks for helping me with tests.

I'm still having health issues so limited to cell phone.

The last problem is easy to solve. In the PS 2017 folder there should be files libfftwXXXXXXX. Please copy them to your PS 2018 folder.
The other problems I'll have to figure out.

Health issue not going away but should be able to program again next week hopefully.
Regards,
RONC

Take your time, get healthy. As they say on every damn flight; help yourself before you try to help others!

The plugin is not in a rush at all. It is a very niche usage scenarios after all. I am disproportionally active in this thread considering I need something like this maybe once per 5 years.

Chain,

Getting healthy probably won't happen but relief might.

I'm disappointed that this plugin might be used only once every 5 years. My aim after fixing code is to demonstrate other uses and there are many if you know what to do. Did you know you can interpolate with it? Spatial filter? Many other things and much faster than space domain for large images.

The only practical usage scenario that I knew of for this filter was for removing/suppressing regular repeating patterns. Something no other filter in Ps can do at the moment.

The typical scenario are scans that either have a paper texture or halftone pattern. Not something I encounter often, but when I do it is the most powerful tool for the job. I do recommend the filter to others as well.

I would be very interested in learning about other interesting things someone might use it for.

And once the two filters are working I might try to see if I can make some sort of Action to help cover up stars faster. They are so symmetrical that I feel like a lot of work gets repeated when covering them. And is solid black the best approach? Hmm...

For v2 I would definitely love to see the filter work as a Smart Filter. The ability to just hit save while painting to have the result update in the main file would help me get better results - to see how each change affects the end result.
